Hydraulics for mobile machines, especially wheel loaders (HYDRAULIC SYSTEM FOR A MABILE MACHINE SUCH AS A WHEEL LOADER)

摘要

The invention relates to a mobile machine with the function of "longitudinal vibration attenuation", in particular to a hydraulic device for a roller.The hydraulic device according to the invention is the same as the hydraulic device in the way of the above announcement,The inner part is divided into two pressure chambers by the piston,At least one hydraulic cylinder capable of starting the tool.A stop valve connecting the first champion of the two pressure chambers through a hydraulic reservoir that can be filled by an injection pipe,And a distribution valve which separates two champions in the hydraulic cylinder and connects the pressurized and / or two champions to an exhaust valve on the tank.In order to reduce the cost and space of the above devices, the first pressure chamber of the oil pressure storage tank and the hydraulic cylinder is connected with each other through the Popper valve of the distributing ballast machine, and the stop type ballast machine is incorporated into the distribution valve.
